High strength, stiff, low friction engineering plastic with good wear properties
Acetal (polyoxymethylene) is a high strength, low friction engineering plastic that has excellent wear properties in both wet and dry environments. Easy to machine, acetal makes an outstanding choice for applications that require complex, tight tolerances.

ACETAL MATERIAL OPTIONS
Homopolymer vs. Copolymer– Acetal is available in both homopolymer (Delrin® 150) and copolymer.
- Homopolymer acetal (Delrin®) has superior room temperature strength, stiffness, and toughness.
- Copolymer acetal has excellent performance in continuous high heat and hot water environments. Copolymer acetal also tends to have less porosity than homopolymer acetal.
FDA Compliant Material– Acetal is available in FDA compliant grades.
Acetal Grades– Acetal is available in a number of grades, including enhanced bearing and wear Delrin® AF, Delrin® 100AF blend, Delrin® AF DE588, and TECAFORM® HPV13. Delrin® 511P is a homopolymer acetal that offers enhanced crystallization characteristics. This higher level of crystallization helps to augment aspects of the physical properties such as fatigue strength, stiffness, and creep resistance.
Ask about special formulations that offer medical, metal detectable, x-ray detectable, or static dissipative grades.
Chemical Attack– Acetal is chemically resistant to many fuels and solvents.
Wear Resistance– Acetal offers good wear and abrasion properties.
Tech Tip– Glass-filled grades of acetal offer enhanced strength and stiffness such as Delrin® 570.
